Lucien Hardy received his PhD at Durham University in 1992 under the supervision of Professor Euan J Squires. He has held research and lecturing positions in various cities across Europe. While in Rome Lucien collaborated on an experiment to demonstrate quantum teleportation. In 1992 he found a very simple proof of non-locality in quantum theory which has become known as Hardy’s theorem.

Time symmetry in operational theories

Lucien Hardy Perimeter Institute for Theoretical Physics

The standard operational probabilistic framework (within which Quantum Theory can be formulated) is time asymmetric.  This is clear because the conditions on allowed operations include a time asymmetric causality condition.  This causality condition enforces that future choices do not influence past events.  To formulate operational theories in a time symmetric way I modify the basic notion of an operation allowing classical incomes as well as classical outcomes.  I provide a new time symmetric causality condition which I call double causality.

Using humans to switch the settings in a Bell experiment

Lucien Hardy Perimeter Institute for Theoretical Physics
I discuss how we might go about about performing a Bell experiment in which humans are used to decide the settings at each end. To get a sufficiently high rate of switching at both ends, I suggest an experiment over a distance of about 100km with 100 people at each end wearing EEG headsets, with the signals from these headsets being used to switch the settings.
